Facility overview
Mayak, near the closed city of Ozyorsk in the Urals, is one of Russia's oldest and largest nuclear complexes. Founded in 1948 to produce plutonium for the Soviet weapons programme, it now carries out spent-nuclear-fuel reprocessing, isotope production and waste management. It is the site of the 1957 Kyshtym disaster, one of history's worst radiological accidents.
Mayak is a reprocessing and production complex operated by Rosatom, not a power station; it generates no commercial electricity. It remains central to Russia's closed nuclear fuel cycle and is a recurring subject in non-proliferation and environmental monitoring.
In context: how this plant compares
Technically it is described as Spent-fuel reprocessing & isotope production. This facility converts its energy source into electricity for the grid; its capacity, fuel type and location determine its role in the national power mix.
Capacity comparison computed from the WRI Global Power Plant Database; fuel-type context is general engineering background.

Climate zone & how it works
This nuclear plant generates electricity for the grid. It sits in a warm-summer humid continental climate (Köppen Dfb) — Northern Hemisphere, latitude 55.7°N — which shapes how much energy it can produce and how its output varies through the year.
